However, there is a reason for hope. There are many clear-cut actions that can help coral reef ecosystems. The Coral Reef Alliance (CORAL) works at multiple scales from local to global to address reef threats. At a local level, when we reduce direct threats to reefs—such as pollution, overfishing or unsustainable tourism—reefs are healthier and more capable of withstanding the effects of climate change, like bleaching and ocean acidification. At a regional and global level, we help reefs by establishing Adaptive Reefscapes – networks of healthy reefs that enable corals to adapt to climate change because they are diverse, connected and large.
